Venting Layout; Wall Mounted Terminations: Top Vent - Montigo H38DF-CLCR Installation & Maintenance Manual

VENTING LAYOUT

Selection of components and details of venting layout should adhere to
the following guidelines:
Vent terminations must not be recessed in walls or siding.

All through-the–wall terminations within 58" Horizontal distance of the

fireplace must have a Montigo Heat Shield (RHS102) installed. See
Section 3-3-3.
All through-the-wall terminations beyond 58" Horizontal distance of the

fireplace must have a Montigo Heat Shield (RHS101) installed. See
Section 3-3-3.
Once the proposed venting layout has been determined refer to either

Figure 15 or Figure 16 to ensure the layout is acceptable.
Wall mounted Terminations
The following details are some possible configurations for Wall
mounted terminations. See below.

Wall Mounted Terminations: Top Vent

All dimension lengths for vertical or horizontal runs are measured from

center of the vent pipe.
Venting runs must fall within the limits set by the venting graphs, see Figure 15.

The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of the termination
and the horizontal run from the fireplace flue collar to the wall flange of the termination.
Plot on the Venting Graph Figure 15 with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the installation is
acceptable.
Example a: (acceptable Installation)
If the vertical dimension from the hearth is 90" and the horizontal
run to the wall flange of the vent termination is 60", this would be
an acceptable installation.
Example B: (acceptable Installation)
If the vertical dimension from the hearth is 60" and the horizontal
run to the wall flange of the vent termination is 36", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and
the horizontal run to the wall flange of the vent termination is 144",
this would nOT be an acceptable installation.
